DetachDomain(domain)

Since: 20220624-141144-bd1b7c5d

Attempts to detach the specified domain. Detaching a domain causes it to disconnect and remove its set of windows, tabs and panes from the local GUI. Detaching does not cause those panes to close; if or when you later attach to the domain, they'll still be there.

Not every domain supports detaching, and will log an error to the error log/debug overlay.

local wezterm = require 'wezterm'
local act = wezterm.action

return {
  ssh_domains = {
    {
      name = 'devhost',
      remote_address = 'devhost.example.com',
    },
  },
  keys = {
    { key = 'U', mods = 'CTRL|SHIFT', action = act.AttachDomain 'devhost' },
    -- Detaches the domain associated with the current pane
    {
      key = 'D',
      mods = 'CTRL|SHIFT',
      action = act.DetachDomain 'CurrentPaneDomain',
    },
    -- Detaches the "devhost" domain
    {
      key = 'E',
      mods = 'CTRL|SHIFT',
      action = act.DetachDomain { DomainName = 'devhost' },
    },
  },
}
